Gown 100 is symmetrical along a vertical center line indicated by reference numeral 22 with first edge 16 and second edge 16′ being equidistant from centerline 22.

The front and rear wall sections 30 and 30 r of gown 100 are bonded or joined together by heat sealing, ultrasonic bonding, induction sealing, or other bonding methods known in the art at various locations or sealed regions as described below for providing a wearable structure. In general, it will be recognized that any of the individual wall sections 30 or 30 r as well as any sealed regions provided in gown 100 are configured to have adequate and sufficient mechanical, physical and barrier properties under general conditions of use typically required for isolation gowns and as may be required by applicable regulatory standards for the intended purpose. In embodiments, gown 100 is configured as a non-surgical isolation gown. In other embodiments, gown 100 is configured as a surgical isolation gown. In still other embodiments of the invention, gown 100 is configured for splash protection from liquids at home, work, and in industrial settings.

In embodiments, gown 100 is configured to meet or exceed the requirements promulgated by American National Standards Institute (ANSI) and the Association of the Advancement of Medical Instrumentation (AAMI) under ANSI/AAMI PB70:2012 standard (the “PB70 Standard”), which addresses liquid barrier performance and classifies a gown's ability to serve as a barrier to penetration by liquids or liquid-borne pathogens. The PB70 Standard has also been formally recognized by the US Food and Drug Administration (US FDA). The PB70 Standard defines critical protective zones for surgical and non-surgical gowns and establishes four levels of barrier protection, namely, Level 1 (Minimal risk; basic care), Level 2 (Low risk; veinal blood draw, ICU, pathology lab), Level 3 (Moderate risk; arterial blood draw, emergency room, trauma), Level 4 (High risk; pathogen resistance, non-airborne infectious diseases, long duration fluid exposure).

The front panel or wall section 30 of gown 100 includes a leading front edge 14 and a trailing front edge 12. In the embodiment shown in FIGS. 2 and 3, the leading front edge 14 of tube 50 forms the lower front edge of gown 100, while trailing front edge 12 forms the upper front edge of gown 100. Similarly, rear wall section 30 r of gown 100 includes a rear upper edge 12 r and rear lower edge 14 r. The front and rear bottom edges 14 and 14 r of gown 100 can be pulled apart for separating wall sections 30 and 30 r for donning or wearing gown 100. The rear wall section of gown 100 is not visible in FIGS. 2 and 3 but is partially visible in FIG. 4.

Gown 100 can be separated from the tube 50 at front and rear top edges 12 and 12 r by shearing, perforating, or cutting through the tubular front and rear wall sections 30 and 30 r. As shown in FIG. 2, the front top edge 12 of gown 100 separates gown 100 from the next gown 100 n in the tubular structure or tube 50. Accordingly, a series of gowns can be derived from tube 50 in succession. FIG. 3 shows gown 100 in a flat configuration apart or extracted from tube 50.

Gown 100 includes a left sleeve 44 and a right sleeve 44′, wherein the sleeves 44 and 44′ are symmetrical about center line 22 and configured for accommodating and covering the wearer's arms including the wrist region of the wearer. Left sleeve 44 is defined by an upper sealed region 20 and a lower sealed region 24. Similarly, right sleeve 44′ is defined by an upper sealed region 20′ and a lower sealed region 24′. Sleeves 44 and 44′ are substantially straight with uniform sleeve gap between upper and lower sealed regions indicated by arrow 36. It will be thus realized that in the straight sealing configuration of sleeves 44 and 44′, the width of the tubular structure or distance between edges 16 and 16′ is configured to accommodate the arm-span of a human wearer and gown 100 can be made in a variety of sizes according to the arm-span(s), trunk size(s) and height(s) of the wearer(s).

Gown 100 includes a neck opening 42 that is centrally located between the upper sealed regions 20 and 20′ of sleeves 44 and 44′ respectively. The upper sealed region 20 does not extend all the way to edge 16 and a relatively narrow gap 40 is provided in sleeve 44 between sealed region 20 and edge 16 for enabling a wearer to insert their hand therethrough for donning the gown 100. Similarly, gap 40′ is provided in sleeve 44′ between sealed region 20′ and edge 16′ for enabling the wearer to insert their other hand therethrough. In an alternate donning procedure, gaps 40 and 40′ can be utilized as thumb loops and the wearer pierces through the closed edges at the distal ends of sleeves 44 and 44′ for creating openings for the remaining fingers.

The lower sealed regions 24 and 24′ of sleeves 44 and 44′ extend inwardly from edges 16 and 16′ respectively and terminate at respective armpit areas 46 and 46′. The sealed regions 24 and 24′ are of equal width and symmetrically located about centerline 22 and are spaced apart from each other by gap 38 that is configured for accommodating the wearer's torso area. As shown in FIGS. 2 and 3, gown 100 also features sealed regions 26 and 26′ that are proximate and parallel to sealed regions 24 and 24′ respectively. Sealed regions 26 and 26′ also extend inwardly from edges 16 and 16′ respectively. Sealed regions 26 and 26′ are also referred to as auxiliary sealed regions. In between sealed regions 24 and 26 there is provided a perforated section 32 that allows severing of the gown material along the frangible perforations for separating the sleeve 44 from the excess material below the sealed region 26. The excess material below sealed region 26 is denoted by flap 52 (explained further in reference to FIG. 4). The perforated section 32 is configured to be of shorter length than the sealed regions 24 and 26 so that the perforated section 32 does not extend to the sleeve armpit upon separating the sleeve 44 from the rest of the gown material.

Sealed regions 24′ and 26′ bear a symmetrical relationship to regions 24 and 26, respectively. In between sealed regions 24′ and 26′ there is provided a perforated section 32′ that allows severing of the gown material along the frangible perforations for separating the sleeve 44′ from the excess material below the sealed region 26′. The excess material below sealed region 26′ is denoted by flap 52′ (explained further in reference to FIG. 4). The perforated section 32′ is configured to be of shorter length than the sealed regions 24′ and 26′ so that the perforated section 32′ does not extend to the sleeve armpit upon severing of the sleeve 44′ from the rest of the gown material. Perforated sections 32 and 32′ are also referred to as underarm perforated sections.

It will be apparent from the above description that sealed regions 20, 24 and 26 are co-symmetric with correspondingly respective sealed regions 20′, 24′ and 26′ about centerline 22. In the exemplary embodiment shown in FIGS. 2 and 3, symmetric pairs of sealed regions—20 and 20′, 24 and 24′, 26 and 26′ are shown in a single-lip-seal format for illustrative purposes, however it will be realized by those skilled in the art that any one or more of the sealed region pairs can utilize a variety of design configurations such as—thin lip, thick lip, single lip, dual lip, or combinations thereof.

The inner surfaces of gown 100 can be accessed by pulling apart front and rear bottom edges 14 and 14 r and separating wall sections 30 and 30 r for donning and wearing gown 100.

FIG. 4 shows gown 100 in a ready-to-wear state with front wall section 30 and rear wall section 30 r shown in a pulled apart state revealing both the front bottom edge 14 and rear bottom edge 14 r. Neck opening 42 created by the unsealed portion between upper sealed regions 20 and 20′ is configured for accommodating the wearer's neck by separating front top edge 12 and rear top edge 12 r. First and second sleeves 44 and 44′ respectively are shown in a detached state from the rest of the gown material for facilitating donning and using gown 100. Sleeves 44 and 44′ are separated from the gown material by severing along perforated sections 32 and 32′ (shown in FIGS. 2-3). The proximal end of sealed regions 24 and 26 defines first armpit area 46, whereas the proximal end of sealed regions 24′ and 26′ defines second armpit area 46′. Extra gown material below sealed regions 26 and 26′ forms flap 52 and 52′ that can be wrapped around the wearer's body to complete donning of gown 100 (best shown in FIG. 6). The gaps 40 and 40′ can be utilized by the wearer for penetrating their hands through the closed edges at the respective distal ends of sleeve portions 44 and 44′.

FIG. 5 illustrates gown 100 after donning by wearer 80 showing a donning option according to an embodiment of the invention. The unsealed portion or gap 42 between sealed regions 20 and 20′ is adapted for accommodating wearer's neck 84. Sleeves 44 and 44′ are configured for accommodating wearers arms including the wrist region of the wearer. The gap or unsealed portion at the distal end of the sleeves 44 and 44′ is shown penetrated by wearer's hands 82 and 82′. The extra gown material in forms of flaps 52 and 52′ is secured in the rear as further explained below.

FIG. 6 illustrates the rear or back side of gown 100 after donning by the wearer showing a donning option according to an embodiment of the invention. It will be realized that in the rear view of FIG. 6, the numerical references with prime symbol suffixes are shown on the left side of the illustration. As shown, flap 52′ is wrapped around the rear of gown 100 over flap 52, wherein flaps 52 and 52′ are secured to the rear wall section 30 r with at least one adhesive tape closure or tape 54. As shown, the adhesive tape 54 is shown placed closed to the center line of the gown 100 on rear wall section 30 r and partially covering sealed regions 26′ and 26. In other embodiments, adhesive tape 54 can be placed at other locations for securing flaps 52 and 52′ depending on the range of motion of the wearer or comfort level for attaching the adhesive closure. The gown can be doffed or removed after use by tearing through the front panel or the rear panel.

In alternate embodiments of the invention, flaps 52 and 52′ can be manipulated and secured in a variety of configurations including—securing the flaps in rear by employing a plurality of tape closures at multiple locations; securing the flaps in the front with one or more tape closures to provide extra layers of splash protection; and securing one of the flaps in the front and one of the flaps in the back to provide extra protection at both the front and the back of the wearer. Flaps 52 and 52′ can also be left loose on the sides.

FIG. 7 shows gown 110 according to another embodiment of the invention derived from tube 50 showing an alternate sealing arrangement to gown 100. In gown 110, the leading front edge 14 of tube 50 forms the upper front edge of gown 110 and trailing front edge 12 forms the lower front edge 12 of gown 110. Accordingly, in FIG. 7 the machine direction is shown with arrow 51 pointing vertically upright towards leading edge 14. In the embodiment shown in FIG. 7 the sleeves 44 and 44′ are located proximate the leading front edge 14 which forms the upper front edge. The construction of gown 110 is otherwise similar to gown 100 except for the sealing arrangement relative to the leading and trailing edges. The next gown in the series from tube 50 is denoted by 110 n and the upper sealing regions 20 n and 20′n of gown 110 n are also visible in FIG. 7.

FIG. 8 shows gown 120 according to still another embodiment of the invention that is also constructed from tube 50 and has a similar construction to gown 100, except that it features a modified sealing configuration of the sleeves. In the embodiment shown in FIG. 8, gown 120 includes dual lip sealed regions 25 and 25′ having distal ends at side edges 16 and 16′ and proximal ends at armpit areas 46 and 46′ respectively.
